Im not sure how far from blue lake is from boise, i usually come from the other direction. It is about 1/2 hour from Wendover... That makes it roughly.. 4 hours? look at your map is about the best I can tell you. for food and accomodatins, wendover is your only nearby town.
The lake is a small oasis in the middle of nothing, there are no trees or any facilities around, sometimes there might be a club that has set up a wind break, or brought a large tent or camper that can help... there are no fills, We bring a compressor, or several tanks. I never have hit up the wendover fire dept about filling from their scba system, but if you have the proper fittings you could try that. the nearest Dive shop to the lake to my knowledge is Bonneville Sea Base, about 2 hours west of wendover? So come prepared!
Medical assistance, if you need is from wendover, and is SLOW! Last year our club had an underwater heart attack, and they were well over 1/2 hour from scene. but we were lucky and he made a full recovery. : ) your closest chamber I believe is in SLC.
The lake itself is a pretty good dive, considering other divers havnt silted up the bottom. Clarity can be from 20ft to mud... the temperature is in the low to mid 70s. never dove it in the winter, so I cant say how much it fluctuates... Depths range from 6-70 ft. and you are at elevation, so adjust properly, there are alot of "redneck art" at the bottom, some of them are quite impressive, and others not, but it makes for an intersting experience. As far as diving, no nead for a drysuit, ive always wore either a 5 or a 7 and never even gotten chilled. The bottom of the lake is fed by natural hotsprings, and you can warm up verry easily.. but i would bring a dry suit because there is nothing to protect you from the elements on your surface intervals, and the wind can get terrible out there.
hope this helps a lil, if you need driving directions from wendover, gps coordinates or what ever, let me know.
